The camera filter kits have a lot of different options for all pockets. Camera filter Kits from Brands like NiSi Optics Ireland 100mm Natural Density Kits include a Base, Long Exposure and Extreme kit bringing together the most popular NiSi ND filters at a great saving of up to 30% over buying the filters individually. NiSi Neutral Density Filters uniformly reduces the amount of light entering the lens. ND Filters can enable greater motion blurring and image detail by allowing a large aperture and a slow shutter speed. ND filters are also helpful when the contrast between the highlights and shadows is too high to get quality exposure.
